Coupler



The purpose of the coupler is to connect implements to an arm of a vehicle, for example, a bucket to an excavator. The characteristic feature of this coupler resides in the tongue used for connecting and releasing the implement to the arm of the vehicle.

FIG. 1 is a top plan view of the coupler embodying our design;
